Novel heterocyclic flavoring compositions and processes

Abstract

The flavor and aroma of tobacco products are altered by adding thereto an effective amount of at least one N-substituted pyrrole having the formula:

What is claimed is: 
     
       1. A process for altering the flavor and aroma of a tobacco product which comprises adding thereto from about 0.01 to 500 parts per million of at least one N-substituted pyrrole having the formula ##SPC31## wherein R 1  and R 2  are the same or different and represent hydrogen or methyl and R 3  represents alkyl containing eight to fourteen carbon atoms, alkenyl containing three or four carbon atoms, cycloalkyl containing three to twelve carbon atoms, or phenalkyl containing seven to eleven carbon atoms.   
     
     
       2. A process according to claim 1 wherein R 3  is tetradecyl, decyl, octyl, cyclopropyl, cyclohexyl, cyclooctyl, cyclododecyl, allyl, or benzyl. 
     
     
       3. A process according to claim 1 wherein R 3  is n-tetradecyl. 
     
     
       4. A process according to claim 1 wherein R 3  is n-decyl. 
     
     
       5. A process according to claim 1 wherein R 3  is n-octyl. 
     
     
       6. A process according to claim 1 wherein R 3  is cyclopropyl. 
     
     
       7. A process according to claim 1 wherein R 3  is cyclohexyl. 
     
     
       8. A process according to claim 1 wherein R 3  is cyclooctyl. 
     
     
       9. A process according to claim 1 wherein R 3  is cyclododecyl. 
     
     
       10. A process according to claim 1 wherein R 3  is allyl. 
     
     
       11. A process according to claim 1 wherein R 3  is benzyl. 
     
     
       12. A tobacco product comprising tobacco and from about 0.1 to 500 ppm by weight of at least one N-substituted pyrrole according to claim 1. 
     
     
       13. A tobacco product as defined in claim 12 wherein said pyrrole is N-cyclopropyl pyrrole. 
     
     
       14. A tobacco product as defined in claim 12 wherein said pyrrole is N-cyclooctyl pyrrole. 
     
     
       15. A tobacco product as defined in claim 12 wherein said pyrrole is N-tetradecyl pyrrole.
